That Chinese plushie seller on Amazon that released the Spikes and Crackles a while back has apparently expanded stock. I don't have the slightest clue how they are mass producing these things, or where they are coming from, but having seen the Crackle and Spike in real life, they defenitly are reasonable on quality. The proportions are a bit off though in some, as you can see.
Anyway, all of them are here! Buy at your own risk!
Thanks to Maximillian for the heads up!
